    摘要: A valve timing control apparatus of an internal combustion engine includes an output element having a central bore and in mesh with an adjusting member which reciprocates between two axially spaced end positions, thereby defining two pressure compartments which are fluidly sealed from one another. An oil guide bush is received in the central bore of the output element and projects in a bore of the camshaft or the component securely fixed thereto. A first fluid passageway is formed between an outer surface area of the guide bush and an inner surface area of the driven element for conducting hydraulic medium to one of the pressure compartments, and a second passageway is formed interiorly of the guide bush for conducting hydraulic medium to the other one of the pressure compartments. The guide bush is securely fixed to a screw fastener and so configured as to allow a connection from the interior of the guide bush to the other one of the pressure compartments. By separating the unit of guide bush and screw fastener from the valve timing control apparatus, the driven element of the valve timing control apparatus now possesses only a very small axially projecting length so that no additional structural space is required between the outer and the first end wall of the cylinder head. Only after installing the apparatus together with other components of the control mechanism vertically in the form of a cartridge is the screw fastener with attached oil guide bush inserted for securement of the apparatus to the camshaft.

The drive pinion (4) is made up of a circumferential wall (7), a camshaft-distal side wall (8) and a camshaft-proximate side wall (9), which walls (7, 8, 9) together define a hollow space (10) in which at least one hydraulic working chamber is formed by at least two limiting walls (11). The winged wheel (5) comprises at least one wing (14), and each wing (14) divides a hydraulic working chamber into two hydraulic pressure chambers. In accordance with the invention, the camshaft-proximate side wall (9) of the drive pinion (4) is configured as a weight- and design space-saving thin-walled component which is shaped out of a circular blank and comprises a bent edge region (17) that is bent at a right angle and partially surrounds the circumferential wall (7) of the drive pinion (4), said camshaft-proximate side wall (9) being undetachably fixed to the drive pinion (4) by a separate connection (18).
